Do I Need a Humidifier?
Not everyone needs a humidifier, but there are some signs that you might. These include:
- Having dry air in the house.
- Chronic runny nose.
- Hay fever.
- Nose bleeds.
- Asthma and allergy attacks.
- Sinus congestion.
- Dry throat.
Ideal Indoor Humidity
Place the hygrometer in the room you want to check and follow the instructions. The hygrometer will give you a percentage.
If the humidity level is less than 30%, it’s too low and you should get a good humidifier. If it’s above 50%, it’s too high and therefore, you need more air circulation. You can do this by opening windows or buying a dehumidifier (2).
What Size Humidifier Do I Need?
Each humidifier is designed for a different room size. The manufacturer will specify the square footage the humidifier is made for. If you need humidity throughout your home, you will need an entire home humidifier, which we can recommend to you in this article.
Types of Humidifiers
When it comes to buying a humidifier, don’t be fooled into buying the first one you see. There are lots of different types all intended for different purposes. That’s why it’s important you read through this article to find the best one for you, your needs and your home.
We’ll share four types of humidifiers with you.
Ultrasonic Warm or Cool Mist.
Ultrasonic cool or warm mist humidifiers offer both warm and cool mist. Warm mist is great for winter, because it heats up the room a little. Cool mist is ideal all year round, especially in the summer.
These humidifiers are quiet because there are no fan or steam noises. The plates inside vibrate at a high frequency to propel tiny water droplets which create a mist.
- Warm and cool mist option.
- Can leave white dust.
- High maintenance.
Evaporative Cool Mist.
Evaporative humidifiers evaporate moisture through a wicking filter. They’re less messy than other types of humidifiers. In essence, the fan pulls in the air from the room and blows it through the wicking filter. Some of the water evaporates, and some of the water is added to the air to help with low humidity.
Because of the cool mist, these are ideal for homes with pets and children. There is no risk of burning yourself like there is with a warm mist humidifier.
- Less messy.
- Low maintenance.
- Ideal for homes with children and pets.
Air washers increase humidity levels while cleaning the air. Win-win! The water and rotating discs remove impurities such as dust and pollen. In return, the humidifier returns humidified air back into the room.
The main problem with this type is that they are high maintenance. They require frequent cleaning.
- Cleans and humidifies the air.
- Removes dust and pollen.
- High maintenance.
- Need frequent cleaning.
Steam Vaporizer Warm Mist
This humidifier has a fancy heating element so that the water is warmed before it releases into the air. The big benefit to this is that the hot water kills bacteria and organic compounds that you don’t want in your house.
Of course, these pose a safety risk because of their high heat. So if you have children, avoid a steam vaporizer humidifier.
- Warms the air.
- Kills bacteria and organic compounds.
- Good for flu symptoms.
- Safety risk.
- Not energy efficient.
Choosing the Best Humidifier
Getting down to business, how do you choose the best humidifier for you?
First, consider your room size. This is the key element to deciding which humidifier to choose. Check the square footage of your room to make sure it pairs with the square foot coverage of the humidifier.
In general, for small and medium sized rooms, a tabletop humidifier is a good choice. For large rooms, console humidifiers are grand because they generate a lot of air through their spacious water tanks.
If you choose the wrong size, you could end up with too little or not enough moisture in the air. Not ideal.
Next, we recommend you think about simplicity. It’s a good idea to get one that is easy to move around in case you want to rearrange furniture or move it between rooms.
You also want to check how simple it is to replace the wick, change the filters and clean your humidifier. If it’s too much of a hassle, it’s going to get annoying.
Lastly, you want to think about the actual interface of the humidifier. Is it user friendly? If not, we recommend you look at another humidifier.
We’ve mentioned ease of cleaning, but let’s dig a little deeper. In general, humidifiers need to be drained, rinsed and dried daily. This is because bacteria love to grow in moist environments. You definitely don’t want a build up in your humidifier.
If not, the bacteria will just get rereleased into the air after a while. This can have negative effects on you, especially if you have asthma or allergies.
Check the cleaning guide for a humidifier before purchase. Take note of how easy or difficult it will be to clean daily.

Before we get into our product recommendations, let us answer your burning (or rather, humid) questions about humidifiers.
What Is Humidifier Capacity?
The humidifier capacity is the maximum amount of water the humidifier can contain at once. This changes depending on your model. But it’s usually between half a gallon to six gallons of water.
The output is the maximum amount of water the humidifier can emit into the air each day. Most humidifiers have a higher output maximum than capacity maximum. How long this takes depends on the speed setting you choose.
How Do I Add Water to the Humidifier?
Adding water to your humidifier is essential. Once you’ve cleaned the reservoir, fill it back up with distilled water. Some humidifiers will specify that tap water is okay. However, distilled water is free of any additives, so it is always best.
Your humidifier should have a maximum capacity line for the amount of water necessary. If a filter needs to be added directly to the water, do it now.
How Often Will I Need to Refill My Humidifier?
The bigger the tank, the less often you need to refill your humidifier. If you choose a smaller humidifier, like a portable one, and use it throughout the day and night, plan to refill it about every 24 hours.
Alternatively, if you use the humidifier sparingly, this can also limit the amount of times you need to refill it.
Ultimately, it all depends on which model you choose, so read the manufacturer’s guide.
Can I Use Hard Water to Fill My Humidifier?
If you live in a hard water area, you’ll need a humidifier that includes a mineral cartridge. These absorb the mineral content to reduce the spread of these minerals back into the air. You will also need to clean your humidifier and cartridge frequently.
If you don’t have a mineral cartridge, then switch your hard water for distilled water.
Can I Use Essential Oils in My Humidifier?
You guessed it: read the manufacturer’s guide. It will tell you if your specific humidifier works with essential oils.
It is a lovely thought that you could scent your air while adding moisture. So you might want to choose an aroma diffuser. If you do, add a few drops of your favorite essential oil to the water tank for a pleasant humidifier experience.
